I think you are after the clip that covers the join between the lower molding and the corner, yeah?
This clip is part of the WEATHERSTRIP ASSEMBLY.
If I search my car, I find this:
68210C WEATHERSTRIP ASSY, FRONT DOOR GLASS, OUTER LH
This part shown is for a front door, because I have an extracab, and I think you have a dual cab(?). So you need to search your VIN to find your particular correct part number. I use: https://www.toyodiy.com/parts/q.html
Then only 1 car should come up, yours. Click that link, then go to the search box upper right, and enter: WEATHERSTRIP ASSY. A list should come up, showing the bits you need.
It looks like you can buy all 4 assy's as a kit on ebay..
